ANALOG DEVICES LTC2657BIUFD-L16#PBF Digital to Analogue Converter, Octal, 16 bit, 2 Wire, I2C, Serial, 2.7V to 5.5V, QFN, 20 Pins

LTC2657BIUFD-L16#PBF is a octal I²C 16bit, rail-to-rail DAC. This DAC has built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2657-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. This DAC can also operate with an external reference, which sets the full-scale output to 2 times the external reference voltage. This part uses a 2-wire I²C compatible serial interface. The LTC2657 operates in both the standard mode (maximum clock rate of 100KHz) and the fast mode (maximum clock rate of 400KHz). The LTC2657 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale at power-up. If PORSEL is tied to VCC, the DACs reset to mid-scale at power-up. Applications include mobile communications, process control and industrial automation, instrumentation, automatic test equipment, automotive.
